“…Porous solid materials and biosorbents such as activated carbon, silica gel, molecular sieve, activated alumina biolms, algae and so on as adsorbents are used to remove heavy metals in water. [1][2][3][4] The low-cost biolm adsorbents show the great removal of Cr(II) in aqueous solution, with -NH 3 and -OH groups dominating. 5 However, biolms have strict temperature requirements.…”

Phosphosilicate (SiPh)/hyperbranched polyamidoamine (HYP)/Erbium (Er+3) hybrid nanocomposite (SiPh‐HYP‐Er+3) was prepared as novel optical planar waveguide material in two different forms, monolith and thin film. HYB was synthesized by one‐pot polymerization reaction via couple monomer methodology. Afterward, SiPh‐HYP‐Er+3 nanocomposite was prepared by doping the HYB and Er+3 nitrate into phosphosilicate matrix by using sol–gel technique. The prepared (SiPh‐HYP‐Er+3) nanocomposite was characterized by Fourier transform infrared (FTIR), X‐ray diffraction (XRD), the field emission scanning electron microscopy (FESEM), and high‐resolution transmission electron microscopy (HRTEM). Adjustable refractive indices (RIs) have been calculated for SiPh‐HYP‐Er+3 nanocomposites. The Vis–NIR photoluminescence emission spectra for monolith and thin film of SiPhEr+3 and SiPh‐HYP‐Er+3 nanocomposites under excitation of Ar‐Laser with 514 nm wavelength were dominated by an emission band centered at around 1.54 µm region. That band was assigned to 4I13/2 → 4I15/2 transition and the 4f‐transition state of Er+3 ions which was influenced by the presence of the hyperbranched polymeric material leading to coordination and Er+3 ions complex formation with the hyperbranched polymers.

“…In some of the studies, it was reported that there is a surprising relationship between their adsorption capacity and increasing generations of PAMAM. While it is expected that higher generation dendrimers may show better adsorption efficiency owing to higher density of binding locations, their efficiency was conversely determined to decrease as the steric hindrance takes place at high generation of dendrimers [ 28 , 36 , 37 , 38 ]. Therefore, 1 st and 2 nd generation dendrimers were used instead of 3 rd generation dendrimers in the preparation of nanostructured adsorbents in this study.…”

In this study, new, efficient, eco-friendly and magnetically separable nanoadsorbents, MNPs-G1-Mu and MNPs-G2-Mu, were successfully prepared by covalently grafting murexide-terminated polyamidoamine dendrimers on 3-aminopropyl functionalized silica-coated magnetite nanoparticles, and used for rapid removal of lead (II) from aqueous medium. After each adsorption process, the supernatant was successfully acquired from reaction mixture by the magnetic separation, and then analyzed by employing ICP-OES. Chemical and physical characterizations of new nanomaterials were confirmed by XRD, FT-IR, SEM, TEM, and VSM. Maximum adsorption capacities (q m ) of both prepared new nanostructured adsorbents were compared with each other and also with some other adsorbents. The kinetic data were appraised by using pseudo-first-order and pseudo-second-order kinetic models. Adsorption isotherms were found to be suitable with both Langmuir and Freundlich isotherm linear equations. The maximum adsorption capacities for MNPs-G1-Mu and MNPs-G2-Mu were calculated as 208.33 mg g −1 and 232.56 mg g −1 , respectively. Antimicrobial activities of nanoparticles were also examined against various microorganisms by using microdilution method. It was determined that MNPs-G1-Mu, MNPs-G2-Mu and lead (II) adsorbed MNPs-G2-Mu showed good antimicrobial activity against S. aureus ATTC 29213 and C. Parapsilosis ATTC 22019. MNPs-G1-Mu also showed antimicrobial activity against C. albicans ATTC 10231.
